Energetic characterisation of transient clustering dynamics in aggregation-diffusion systems
Nathalie Wehlitz, Richard Scherzer, Carsten Hartmann +1
We investigate transient clustering dynamics in nonlocal aggregation-diffusion systems from an energetic perspective. Starting from a stochastic interacting particle system, we stu…

A fast and rigorous numerical tool to measure length-scale artifacts in molecular simulations
Benedikt M. Reible, Nils Liebreich, Carsten Hartmann +1
The two-sided Bogoliubov inequality for classical and quantum many-body systems is a theorem that provides rigorous bounds on the free-energy cost of partitioning a given system in…

Computationally feasible bounds for the free energy of nonequilibrium steady states, applied to simple models of heat conduction
Luigi Delle Site, Carsten Hartmann
In this paper we study computationally feasible bounds for relative free energies between two many-particle systems. Specifically, we consider systems out of equilibrium that do no…
